nn'raeniinrin RUBBER einen Application filed June 15, 1921. Serial No.177,312-` i To all w 710m it m07/ com-ern.

Be it known that l lVILLniM A. MALoNnY,

a citizen of the United States' residing at Newton, inthe county otMiddlesex land VState of Massachusetts, have 'invented a new and usetulletachable Rubber Heel7 ot which the following is a specification.

This invention relates to a detachable rubber heel and Vparticularly toimproved devices forva'ttaching the heel to a shoe. 1t is the generalobject ot my invention to provide attaching devices of simpleconstruction, so designed that they maybe economical in manufacture,reliable in service and easily attached `or detached as desired.

My invention further relates to arrangements and combinations of partswhich will behereinaiiter described and more particularly pointed out inthe appended claims.

A preferred 'lorin ot my invention isA shown in the drawings in which-Fig. 1 is a partial side elevation of a' shoe showing my detachable heelconstruction in sectional elevation7 taken on the line 1 1 in Fig. 2;

Fie. 2 is a plan view of the detachable heel;

Fig. 3 is a bottom view of the heel litt to i to Fig. i but showsecuredthereto in any usual or desired many ner. The lift 11 is provided with aplurality of recesses 12, certain of these recesses being surrounded bywashers 1S embedded in the material of the heel lift which is preferablymade of hard rubber.

The heel 14 is provided with a plurality of integral projections 15located to correspond with the recesses 12 in the heel litt. Metalplates 16 are molded in the body oi' the heel, these platesbeingassociated with certain @t the projections 15 and having upwardlyextending toothed portions 17 each preferably embedded or partiallysurrounded by its associated projection. Slots 18 (Fig. 3) may beprovided at the edges of projection 17 therein.

the recesses 12 to permit the entrance of the The heel is secured to theheel litt by' simply inserting the projections 15 in the recesses 12and't'orcingthe parts together until the teeth of the portions 17 engagethe .inneredges of the corresponding washers Theparts I 13,'as clearlyshown in Fig. 5.- are thus i'rinlyfheld together at a number ofseparated points and the heel cannot be accidentally displaced. j

I provide, however, for the removal of the heel by forming two openingsy19 in the breast of the lieellift 11, these openings eX'-l tendingintorthe inner ends of two of the recesses 12 and permitting theinsertion of rods' 20 (Fig. 5) to forcethecorresponding toothed portions17 rearward andthus dis-V engage the teeth from lthev washers 13. Whenthe front edge'of the heel is thus treed., the entire 'heel may beremoved .byV bending the heel downward from the front,

edge. The resilience of the projections 15 yieldingly holds the toothedportions 17 in engagement with the washers13 but permits the portions 17to be forced backward to release vthe heel.

It will thus appear that l have provided an extremely simple andreliable construction by which a heel may be detachably ses cured to ashoe without the use vof any separately movable parts. lt will befurther evident that changes and modifications can be made inmyinvention by those skilled in the art within the spirit and scopethereof as set forth inthe claims and I do not wish to be otherwiselimited to the details herein dis'- closed but what I claim is 1. In ashoe7 a heel litt and a rubber,

heel detacliably secured thereto, said lift having a plurality ofrecesses bordered by rigid members and said heel having integralprojections corresponding in size and position to `said recesses andhaving upwardly Vextending toothed plat-es associated with saidprojections and effective to engage said j rigid members and to secure.the heel in position each projection cooperating with its as-y sociatedplate to hold the same in locking recesses and having also a pluralityof plates 'of approach with the parts in normal and substantially flatposition.

3. n a shoe, a lieel lift and a rubber heel detaehably seeured thereto,said lift haring a plurality ot recesses bordered by rigid members andsaid heel having toothed plates V`embedded therein and extendingupwardly therefrom,

said plates engaging said members when the parts are yieldinglyassembled by a direct movement or' approach and preventing separationthereof, and said vlift YhavingV openings communicating Withcertain ofsaid recesses to facilitate separation or said plates and members.

4.111 a shoe, a heel lift and a rubber heel detachably secured thereto,said lift having a plurality of recesses bordered by' metal Washersembedded Y in said lift and spaced from the face thereof and said heelhaving` a plurality of plates fixed therein With'toothed projectionsextending upwardly at right Y angles to said heel and plates andengaging the inner edges of said Washers tosecure the heelin position,said parts being yieldingly assembled by a directJ movement of approachandbeing positively held Vfrom separation.

In testimony whereof, l have hereunto affixed my signature. Y'
